Yes, a small part. The part that will write out the RAID information
(thus updating the generation) whenever the status changes,
regardless of whether that change takes place when the machine is off
or not.

I am fairly astonished that the ataraid code didn't do that already :(

Without testing, I can't be sure whether this solves the problem on
other ataraid devices.

I don't have ready access to such systems anymore, we switched to 3ware
controllers after seeing problems with broken arrays.
